IPC: B65D5/54
Filed: 1968-04-01
Abstract: 1,251,071. Boxes. UNILEVER Ltd. 28 March, 1969 [1 April, 1968], No. 15497/68. Heading B8P. A protective case for liquid containers is erected from a blank of corrugated board providing side walls 1, 2, 3, 4, overlapping base flaps 7, 8 and closure flaps 11, 12, 13, 14, one, 13, having an aperture 16 for the neck of the container, this flap being connected to the adjacent flaps by gussets 18, 19. The edges 5, 6 are secured by adhesive tape. There are handholds 2a, 4a and 26a, and a hinged flap 17 facilitates insertion of the neck of the container into the aperture 16. The gussets are formed by folds 20, 22, 24 and 21, 23, 25. The handle 26a is hinged to the flap 13 at 27 and a cover 28 is hinged to that at 29. The opposite top flap 11 has a slot 33, matching at slot 34 in flap 28 for the reception of lugs 35 on the remaining flaps 12, 14. Also in these flaps there are perforations 42 forming removable portions 43. The base flap 8 has lateral portions 9, 10 lying against the side walls. An edging 31 on flap 11 is folded under (Fig. 4, not shown) and the flap itself engages the gussets 18, 19 under the flap 28. Tabs 39 are folded at lines 40, 41 so that the tabs lie adjacent the aperture 16 in flap 13 and so prevent the container being opened while there is a container-neck projecting from the aperture 16. This is torn off at perforations 42 to give access to the closure and the handle 26a is uncovered for pouring. This arrangement prevents pilfering.

Abstract: 1,251,796. Measuring force electrically. EMI Ltd. Nov.4, 1968 [Nov.2, 1967], No.49873/67. Heading G1N. A force balance comprises a first lever 4 arranged to be deflected by a force to be measured and coupled by slug 6 and inductances 7, 8 to an electrical circuit supplying a balancing coil 15 which tends to restore the first lever towards its undeflected position, the arrangement of the coil and the first lever being such that the magnitude of the restoring force is smaller than the force to be measured, wherein a balancing mass 17 is coupled to the first lever by a secondary lever 18 so as to reduce the static imbalance of the first lever and coil. In an alternative embodiment, Fig. 3, the secondary lever is replaced by two levers 23, 24 on opposite sides of and equispaced from the line 21 representing the arm of the first lever between the coil and the pivot 5. The levers are connected to bell cranks 28, 29, 30 by flexible links 37, 38, 39 and extensions 34, 35, 36, the cranks being pivoted at 31, 32, 33. As illustrated in Figs. 5 (not shown) clockwise angular displacement of levers 23, 24 imparts substantially equal counterclockwise displacement of arm 21. Thus the force balance is compensated against errors arising from angular acceleration. It is shown that if the levers are of equal lengths the system will be statically balanced. The balance is applied to measurement of gas pressure at 2 utilizing a bellows 1.

Title: Coding arrangements for pulse code modulation systems

Abstract: 1324261 Non-linear analogue/digital converter GENERAL ELECTRIC CO Ltd 19 April 1971 [26 Fob 1970] 9405/70 Heading G4H In a non-linear analogue/digital converter in which a sampled analogue input is converted to a time interval, a code generator delivering parallel coded outputs is started at the start of the time interval and a store 13 (Fig. 1), 29 (Fig. 5) is set to the state of the code generator at the end of the interval. The coded outputs are progressively compressed in time towards the start of the interval to give the required non- linear characteristic. In the embodiment of Fig. 1 an analogue input V at terminals 1 is fed via a transformer 2, low pass filter 3, phase splitting transformer 4 and sampling transistors 5, 6 to capacitors 8, 7 which store the sample V and its inverse - V respectively. Comparators 10, 9 compare the stored signals with a ramp signal D, the polarity bit first being detected by disabling comparator 9 and comparing the signal V stored on capacitor 8 with Ov. If the comparator 10 delivers a signal at this time gate 14 is enabled to store a "1" bit in the most significant position of store 13. An output is obtained from one of the comparators at equality between one of the stored signals and the ramp signal at which time the store 13 is primed to receive the parallel signal on leads C2-C8. These signals (Fig. 3, not shown) are divided into seven linear portions chosen to give the logarithmic curve of Fig. 4 (not shown). In a modification (Fig. 5) in which the code generator has only four linear portions but the converter characteristic has fifteen linear portions the stored signals V, -V are additionally amplified by sixteen in amplifier 26 and these amplified signals are also compared with the ramp. The polarity bit is determined by initially inhibiting the comparator 19 receiving the signal - 16V and using the output of comparator 20 receiving the signal 16V to control a gate 33 connected to the most significant stage of store 29. The second bit is determined at the end of each cycle by gate 32 being enabled if one of the amplified inputs is greater than the ramp i.e. the second bit is "1" if V>V max / 16 . The remaining bits are determined by the time during one cycle at which one of the comparators enables via OR gate 28 the store 29 to receive the output signals C3-C8 from the code generator. A plurality of devices as in Fig. 1 or Fig. 5, may be connected to a common code generator (44, Fig. 8, not shown) at the end of each cycle the data in each store being read out together with synchronizing data to an associated store in a chain of shift registers from which the bits are serially transmitted via a bipolarizer (41) to a receiver.

The arrangement shown in Fig. 3 is used with the above. For calibration, clean air at a known flow rate is bubbled through mercury contained in cells 11 and 12 the cells being immersed in a thermostatically controlled bath 19. The saturated mercury vapour is then diluted with a known amount of mercury free air or other gas passing through T piece 13. This gas stream now containing a known amount of mercury is passed tothe detection system through the 3 way taps 14 and 15. In order to determine the quantity of mercury in a sample gas stream 16, the sample gas stream is passed through a suitable filter 20 to remove particulate matter and is then passed to the detector through 3 way taps 14 and 15, thus cutting off the air stream through cells 11 and 12, and T piece 13. The zero value is found by passing the gas stream through an iodized charcoal filter 17 prior to reaching the detection system.
